Objectives

Narrative objectives1

Functional gastrointestinal disorders are disorders that present with abdominal symptoms in the absence of organic disease. Functional Dyspepsia, a FGID of the upper gastrointestinal tract, is found in about 15% of adults, of whom about 25% receive some form of medical care, and has an important impact on the quality of life of the patient. According to the Rome IV classification, an international diagnostic standard, FD is defined as a condition in which, despite the absence of organic disease, one or more of four symptoms thought to originate from the gastroduodenal region, namely, painful postprandial lethargy, early satiety, epicardial pain, and epicardial burning, appear at least 6 months prior to diagnosis and persist for 3 months before diagnosis. The pathophysiology of FD includes multiple possible mechanisms such as gastrointestinal motility disorders, visceral hypersensitivity, and central nervous system stress response. It is becoming clear that gastrointestinal and duodenal flora other than H. pylori infection are also associated with dyspepsia symptoms. Although it has been suggested that diet may be a cause of dyspepsia symptoms, no study has been conducted to clarify the relationship between diet and gastrointestinal and duodenal microbiota and dyspepsia symptoms because of the complexity of analyzing dietary content. Therefore, the purpose of this study is to conduct a comprehensive investigation of dietary content, gastrointestinal and duodenal microbiota, and H. pylori strain factors as factors related to dyspepsia symptoms.
